THE LONG-TAILED DUCK. 



Har^lda glacialis (Linnreus). 



Although this species is somewhat uncommon in the south and 

 south-west of England, it was exceptionally numerous in the winter 

 of 1887-88 ; but on the west coast it is local, and adults are seldom 

 seen. On the east side, young birds are not infrequent, and two 

 adult males have been shot in East Anglia in June and a female 

 even in July ; while northward this Duck becomes tolerably abun- 

 dant from November to April. In Scotland it is to be met with in 

 winter from Berwickshire to Caithness, and on the west side it is 

 very common in the Outer and Inner Hebrides. In the Orkneys 

 and Shetlands, where the bird is well known by the name of "Calloo," 

 from the loud musical note of the male, it occurs on nearly all the 

 inlets or voes ; there is even some evidence that it has bred on 

 Sanday, and there can be little doubt that it nests occasionally in the 

 Shetlands. To the north and west of Ireland its visits are irregular, 

 and in the south they are exceptional. 



It is probable that the Long-tailed Duck nests, though sparingly, 

 in the Faeroes, and it does so in considerable numbers in Iceland. 

 In Scandinavia it breeds on the streams and lakes of the fells as far 

 south as lat. 60°, though it only becomes numerous to the north of the 

 Arctic circle ; while in winter it is very abundant along the coasts. 

 It also breeds in Jan Mayen, Spitsbergen, Novaya Zemlya, North
